Start a blog with useful portrait/posing/staging tips using some of your products. Search engines find blogs better than regular sites and link your site (a lot) to the blog.

Sell some on eBay to try and increase your exposure.

Advertise on craigslist (?)

Become part of as many photo communities that you can realistically handle, and still be a real part of the contributing member base. As you build relationships and trust that will hopefully lead to sharing your business with folks that would have an interest in your products. However, I would not join communities just to promote your stuff, actually contributing and beig part of the community to help the comminity interest first, then, hopefully, that will lead to opportunities for your target audience to discover what you are doing and what products you are creating.
